Climate DT standard resolution hourly data on single-level or surface, ICON, Control

This dataset contains surface variables from the second generation Climate Adaptation Digital Twin of the Destination Earth initiative. It includes data from the Control Simulation (1990–2000) of the ICON model. This data was regridded from the original HEALPix H128 grid to a regular latitude-longitude grid at approximately 0.44° resolution. The temporal resolution is 1 hour.

The dataset's chunking is optimized for regional and timeseries analysis.

Accessing this dataset requires a Zarr v3-compatible library (e.g., zarr-python >= 3.x). Python users can upgrade via pip install "zarr>3".

Access is restricted to Destination Earth users with Upgraded Access.

How to download the data

The default (and preferred) way to access the data requires accessing the api.earthdatahub.destine.eu domain and a valid API key.

Method 1: quick access

It is possible to include the token directly in the URL.
